About the role
This interview tests whether you can shape a research question into a sound statistical design and defend the analysis from protocol through reporting. The panel will look for careful assumptions, reproducible programming, mature handling of imperfect data and explanations that keep clinical meaning separate from statistical significance.
How to prepare
- Review a study design you influenced and the assumptions you challenged before analysis began.
- Prepare to explain your approach to missing data, multiplicity and sensitivity analysis in plain language.
- Revisit how you validate analysis code, review derived variables and maintain traceable outputs.
- Choose an example where your statistical advice changed a clinical or research decision.
- Practise describing an effect estimate, confidence interval and limitation without relying on jargon.
Common mistakes
- Choosing a model without checking whether its assumptions fit the data and estimand.
- Treating missing observations as a routine cleaning issue rather than a source of bias.
- Equating statistical significance with clinical importance.
- Describing quality control as a final code review instead of a traceable process throughout the analysis.
